INTERNASAL TUBE.

SPECIFICATION forming part of Letters Patent No. 399,985, dated March 19, 1889.

Application filed July 28, 1838.

To all whom, it may concern.-

Be it known that I, DAVID H. GOODWILLIE, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and Improved Nasal Intubation-Tlube, of which the following is a specification, reference beinghad to the accompanying drawings, forming part hereof.

This invention has for its object to provide a means for the treatment of internasal disease; and it consists of a tube of peculiar construction adapted to be inserted within a nostril to correct deformities and cure diseases therein.

In the accompanying drawings, forming part hereof, Figure 1 is a longitudinal central section of my improved nasal intubation-tube. Fig. 2 is a cross-section, and Fig. 3 is an underneath plan, of the same. Fig. 4 is a longitudinal central section showing a modification in the construction of the tube. Fig. 5 is an elevation showing a shaper adapted to be inserted within a metal tube to modify its form. Fig. (3 represents end elevations of different forms of shapers.

The tube is composed of two partsa long neck, a, of uniform dimensions throughout its length, and an enlarged part, head, or bulb, b, at one end of the same. The neck maybe elliptical, circular, oval, or of any special shape in cross-sections; but the elliptical form seems to be the most eliieient. lit the vestibule of the nostril, the opening I) of the same being shown at right angles to the opening a of the neck a, and a continuous passage within the tube joins the two opening a and b. The tube is preferably made of soft india-rubber and when such material is used it can readily be molded into the desired form. Any other suitable elastic mate rial might, of course, be used, and in some cases I prefer to make the tube of a non-oxidizable metal, such as platinum or gold. I have constructed a very efficient tube by using both metal and soft rubber. Such a tube is shown in Fig. 4. The neck 0 is a metallic tube expanded slightly at one end, 0, while the head (Z is composed of soft rubber and fits over the expanded end of the neck. The part of the head which fits over the end of the neck 0 is slightly stretched by being placed The head I) is shaped to Serial No. 281,269. (No model.)

thereon, and by this stretching and the shape of the expanded end the two parts are securely held together. The overlapping parts of the head 61 are thinned toward the edge, as shown, so that the metallic neck and rubber head form one continuous surface. The insertion of the tube within the nostril is accomplished by raising the end of the nose and pushing the tube into the interior meatus, and then releasing the end of the nose and further pushing the tube, so that the head 1) passes into' the vestibule of the nose. The neck a, should be of such length that the tube will be entirely within the nostril when in this position, so that no portion of the tube will be visible externally. The peculiar shape of the head 7) causes it to fit within the vestibule of the nose and securely hold the tube in place.

It is sometimes necessary to modify the size and shape of the passage through the tube to adjust the opening proportionally to adjacent parts of the body and for other purposes. lVith metal tubes I employ a shapingtool for this purpose. (Shown in Figs. 5 and 6.) This tool consists of a head, 9, formed at one end of a rod, at the other end of which is formed or attached a handle, f. The head is so shaped that when pushed within the tube it will shape the tube to the desired cross- Section.

In Fig. 6 several forms of tools are shown which when pushed directly into a tube shape it to their cross section. WVhen irregular shapes are to be produced, these or similar tools may be manipulated to give the tubes the desired shape. These tubes are adapted to be used in the treatment of all nasal diseases in which it becomes necessary to maintain an opening for respiration by artificial means through the nasal passages, or can be used to correct any deformity tending to obstruct the nasal passages. Small rubber tubes are generally used at the beginning of the treatment, and these are changed to larger ones until there is a normal space or the de formity has been corrected. hen this stage of the treatment is reached, metal tubes may be used, as they permit freer respiration. As these tubes are not externally visible, they do not cause an unsightly appearance nor give any visible indications of their presence. They can be constantly Worn without discomfort, and can readily be removed for cleansing and returned to the nostril by the patient.

Having 110W described my invention, What I claim, and desire to secure byLetters Patent, 1s

1. A nasal intubation-tube consisting of a neck and an enlarged part or bulb of elastic material atone end of the same, and provided with a passage extending entirely through it,

IO substantially as shown and described.

2. As an article of manufacture, the nasal intubation-tube consisting of the neck a and the enlarged part or bulb b at one end of the same, made in one piece and of elastic material, substantially as shown and described.
